CALL OPERATIONS

Placing a Phone Call

To make the outgoing calls using your HT812/HT814

1. Pick up the handset of the connected phone.

2. Dial the number directly and wait for 4 seconds (Default “No Key Entry Timeout”); or

3. Dial the number directly and press # (Use # as dial key” must be configured in web configuration).

Examples:

1. Dial an extension directly on the same proxy, (e.g. 1008), and then press the # or wait for 4 seconds.

2. Dial an outside number (e.g. (626) 666-7890), first enter the prefix number (usually 1+ or international code) followed by the

phone number. Press # or wait for 4 seconds. Check with your VoIP service provider for further details on prefix numbers.

Note:

When placing the analog phone that is connected to the FXS port off hook, the dial tone will be played even if the sip account is not

registered. If users prefer the busy tone to be played instead, the following configuration need to be made:

“Play Busy Tone When Account is unregistered” need to be set to YES under advanced settings.

“Outgoing call without registration” need to be set to NO under Profile x settings.

Direct IP Calls

Direct IP calling allows two parties, that is, a FXS Port with an analog phone and another VoIP Device, to talk to each other in an ad hoc

fashion without a SIP proxy.

Elements necessary to completing a Direct IP Call:

Both HT812/HT814 and other VoIP Device, have public IP addresses, or

Both HT812/HT814 and other VoIP Device are on the same LAN using private IP addresses, or

Both HT812/HT814 and other VoIP Device can be connected through a router using public or private IP addresses (with necessary

port forwarding or DMZ).

The HT812/HT814 support two ways to make Direct IP Calling:

Using IVR

1. Pick up the analog phone then access the voice menu prompt by dialing “***”

2. Dial “47” to access the direct IP call menu

3. Enter the IP address after the dial tone and voice prompt “Direct IP Calling”

Using Star Code

1. Pick up the analog phone then dial “*47”

2. Enter the target IP address.

Examples of Direct IP Calls:

a) If the target IP address is 192.168.0.160, the dialing convention is *47 or Voice Prompt with option 47, then 192*168*0*160,

followed by pressing the “#” key if it is configured as a send key or wait 4 seconds. In this case, the default destination port 5060 is

used if no port is specified

Inter-Port Calling

In some cases, a user may want to make phone calls between the phones connected to multiple ports of the same HT81x when it is

used as a standalone unit, without the use of a SIP server. In such cases, users still will be able to make inter-port calls by using the IVR

feature.

On the HT81x inter-port calling is achieved by dialing ***70X (X is the port number). For example, the user connected to port 1 can be

reached by dialing *** and 701.
